lowing is a full, clear, and-exact descriptionl thereof, which will'enable others skilled in the ,art to make and use the same, referencebeing hlidto the accompanying drawings, forming put of this specification, in whieh- ".fliigure 1 is a central longitudinal vertical section of the. radiator. Fig. 2 is a transverse vertical section of the same.

Similar letters of reference indicate like This invention consists in a radiator composed of a series of steam-tubes closed a-t one end and open at the other, having their open ends connected-with one of'theehambers of a two-chambered steam-box with which the steam-inlet pipe is connected, and having arL` ranged within vthem a series ot' smaller'tubes .which are open at both ends,'and connected the purpose of permitting the escape into the latter chamber of any air that. may have en.

tered the rst-mentioned tubes before the ad?! mission ot' steam thereinto and of the' water `which is formed by condensation, the said collectionfchamber being provided with suitable means of egress for'such air and water.

It also consists in 'the arrangement, within the lower tube 'of the first-mentioned series,-of a tube for the returnthereintofand through it to the first mentioned chamber of the water of condensation received in the collectionchamber, that the said water may return to the boiler by gravitation through the steaminlet pipe.

A is the two-chambered steanrbcx, made with a suitable base, B, arranged in an up- -right position, and havin g an upright partition, a., by which it is divided into the two chambers I). and c. The chamber I has connected at its bottom the steam-pipe d, by which 'steam is admit-ted from a boiler arranged i u the base- .ment or cellar of the building, or in any place below the radiator. -The :chamber c` is what term the collection-ch amber,77 and has the air- A valve e for the escape ot' air from the radiator :attached to its upper part.

The chambers l) and c have no' direct communimltion with each other.

` C C are the steum-tubes, closed at one endand opcn atthe other, and having their open ends screwed into tapped vholes in the steambox A, opposite to the partition a, and communieating with the chamber b.' These tubes are straight and arranged horizontally. one above the other, and their closed ends are-supported by being inserted into holes in a post,

D, which, for the sake of symmetry, is made of the same external formas the steam-boXA. There is only onevertical rowof these tubes in the radiator represented but the steam-boxand lpost maybe made wider, und two-or more rows of tubes lused, according to the amount of heati'n gf surface desired.

11E' Ev are the inner and smaller tubes, Vopen at both ends and 'somewhat longer than the tubes G C. These tubes are arranged near the bottoms of the tubesA C C, one end of each being screwed -in'to a tapped hole providedfor its reception in the partition a, and the other being near the closed end of its-respective tube C. A ll of these tubes E E', except that, E', in the lowest of theA tubes C, are hori-l zontal, but that one has a downward inclination toward the closed end of its respective tube'C. v

-When steam is admitted to the chamber lr of the box A, byopening the cockfin the inletpipe d,.it lls the chamber b, and thence enters the tubes C C, driving thev air from the said chamber and tubes to the closed ends of thesaid tubes, whence itlpasses through the. tubes E -E into the collection-chamber c, and

escapes by the-valve e, which is closed, either through that tube into the bottom of the chamber b, and thence -by gravitation through the pipe d to the boiler. The said tube E should be larger than the tubes E on the upf per tubes C. A

The advantages ot' this radiator consist., mainly, in its simplicity of construction and in the free escape provided for-the'air and water ot' condensation, which prevents. tl1eunpleasant ern'eking vnoise so common to most other radiators.

What I claim as my invention, and desire t0 secure by Letters Patent, isf- .1. The combination of the twovehambered box A, thetubes G C, closed atene end anopend .at the other, and the tubes. E E;, open at bot-h ends, the whole arranged substantially as herein specified.

2. The return-tube E, forming a. eommunil cation between the lower pari-.vof the collecting-chamber c, through the lower fsteaurt'ube C and the ehaimber b of the two eha'mbered box A, to permit the return of the 'water of vcondensation from the said collectingeh amber to the boiler,` through the steam-inlet pipe d, 'substantiallyas herein described.
